I'm trying to inject a service into a Livewire component, but when I use constructor injection or the mount method, I encounter the following error:

$apiKeyService must not be accessed before initialization

To resolve this, I switched to using the boot method to inject the service, and it seems to work fine.

My questions are:

Is using the boot method for service injection a good practice in Livewire components?

Will this approach cause any issues like memory leaks, or is it safe in terms of performance and lifecycle management?

protected ApiKeyService $apiKeyService;
public function boot(ApiKeyService $apiKeyService) 
{
        $this->apiKeyService = $apiKeyService;
 }

First of all, injecting a dependency throught the boot() method is neither a good or bad practice, it just depends on your needs.

According to the Livewire Lifecycle hooks documentation, if you need to get some data only once in your component, you can just create a public property and load its data with the mount() method, as livewire will keep the data throught all its lifecycles since it's a public property.

However in your case, since the service is protected, livewire will not save its data throught the cycles if you load it via mount(), so it's totally relevant to use boot() in that scenario.

Will this approach cause any issues like memory leaks, or is it safe in terms of performance and lifecycle management?

As far as I know, lifecycles are well managed and in no case has a memory leak been reported.

The impact in terms of performance is minimal, depending of course on what you are going to load into the boot() method as it is called for each component request.

I hope that helps
